FASTENER FoR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 624,951, dated May 16, 1899.

Application filed November 16, 1898. Serial No. 696,625. No model.)

To all whom it may concern.-

Be it known that-I, RICHARD LEWIS, a subject of the Queen of Great Britain, residing at Llanelly, in the county of Carmarthen, England, have invented certain new and useful Improvements in Looks or Fastening Devices for Bicycles and Similar Vehicles, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to bicycles and similar vehicles; and the object thereof is to provide an improved lock or fastening device which is adapted to be applied so as to hold a brake in operation to prevent the movement of the wheels of the vehicle.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which-.-

Figure 1 is a side View of a lock which I employ for applying the brake; Fig. 2, a similar View, part of the construction being shown in section; Fig. 3, a side elevation of a bolt which forms a part of the lock; Fig. 4, a side view of a key-bolt which I employ; Fig. 5, a side View of a part of the construction shown in Figs. 1 and 2; Fig. 6, a sectional side elevation of a key by which the lock is operated, and Fig. 7 a cross-section on the line 7 7 of Fig. 4.

In the drawings forming part of this specification the separate parts of my improvement are designated by the same letters of reference in each of the views, and in constructing my improved lock for applying the brake I provide a ring or band A, which is adapted to be connected with the handle-bar of the vehicle and which is open at one side and provided with two projecting jaws a, which form a neck through which is drilled a circular hole a through which is passed the tubular barrel B, screw-threaded at one end, as shown at b, and provided centrally with an annular shoulder b adjacent to which, on the screw-threaded end, is formed a cylindrical portion 19 which is not screw-threaded. The cylindrical portion 12 which is not screwthreaded, is of about the thickness of one of the jaws a,and the other jaw is screw-threaded to correspond with the thread I) on the barrel B, and by turning said barrel in one direction said jaws a may be separated, as will be readily understood, the object of this construction being to facilitate the connection of the ring or band A with the handle-bar, it being understood that by turning the barrel B in the other direction the jaws a are drawn together. I

The barrel B is closed at one end and provided adjacent thereto and in one side thereof with a transverse opening (1, through which is passed a key-bolt D, rectangular in crosssection and provided at its lower end with a head 01 and in one side thereof with a notch or recess 01 and mounted in said barrel is a transverse partition-plate H, through which passes a spring-operated bolt E, and on which is wound a spring G, the inner end of which is secured to the bolt E, adjacent to the transverse partition-plate H, as shown at h, and

Figs. 3 and 4, and in Fig. 6 I have shown a key F, comprising a knob or handle f, having a tubular extension f the bore of which is screw-threaded, as shown at f The outer end of the bolt E is also screw-threaded, as shown at e, and in order to operate the bolt E so as to release the bolt D the key F is inserted through the hole 0 in the cap-plate C andconnected with the outer screw-threaded end of the bolt E, and said bolt is turned or drawn outwardly, so as to release the bolt D.

The barrel B is provided adjacent to the end with which the cap 0 is connected with a downwardly-directed shoulder or projection 19 to which issecured a strong contractile spiral spring G,.which is also secured to the head 01 of the bolt D, and in order to operate the brake-lever so as to apply the brake the ring or band A is passed over one end of the handle bar. The barrel B is then passed through the openings a and turned so as to clamp the ring or band securely on the handle-bar. The spring G is then passed around the brake-lever and the key-bolt D inserted into the opening d, adjacent to the end of the barrel, as shown in Fig. 2, and locked therein by the lock-bolt E, and the spring G draws up the brake-lever and applies the brake and locks the vehicle.

The end of the bolt D, adjacent to the notch or recess (1, is beveled, as shown at (1 and When the bolt D is forced into the barrel B the bolt E is forced outwardly by the beveled portion 01 of the bolt D until the said bolt D passes into the barrel, as shown in Fig. 2, after which the bolt E is forced inwardly by the spring G and holds the bolt D in place.

This device is simple in construction and operation and well adapted to accomplish the result for which it is intended and is also COIII- paratively inexpensive.

Having fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. The locking device herein described, comprising a ring or band A, open at one side and provided with parallel projecting jaws, a barrel screw-threaded at one end and passed through said jaws, said barrel being closed at one-end and open at the other, and provided adj acentto the closed end with a transverse opening in one side thereof, a bolt.

which is adapted to be inserted into said opening, said bolt being connected with the opposite end of the barrel bya spiral spring, a spring-operated bolt mounted in said barrel and adapted to engage with said firstnamed bolt, the open end of said barrel being provided witha cap-plate having a central opening, and a key which is adapted to be inserted through said opening and to operate said spring-operated bolt, substantially as shown and described.

2. The herein described locking device, comprising a clamp open on one side and pr0= vided with parallel projecting jaws, a barrel screw-threaded at one end and passed through said jaws, said barrel being provided with a.

locking bolt, and a spring operated bolt adapted to be connected therewith, and said 4 ence of the subscribing witnesses, this 4th day i of November, 1898.

RICHARD LEWIS.
